Attached to the leg piece 10,by suitable hinges 18 (two or more ofwhichare provided). is, a propelleronfin l9 capable? of: swinging in ahorizontalplane through an arc of 90 or thereabout. Further motionbackward being prevented by the leg piece 10, and further motionforwardbeing :pre: vented by the angle pieces 20, of whichlany desired numbermay be provided. The an-, gle pieces are short strips of rigid metal, or

other material riveted to the leg piece at one end, and bein bentintothe form of a right angle as clear yshown in Fig. :2; These may be madeintegral withithe leg pieceif soldesired'thereby eflecting a savmgofmaterial: and weight, as well as labor.
